20 Most Recent Sony Bravia KDL-40V4100 40 in. LCD HDTV - Page 5 Questions & Answers


Kinda points to power supply . Does it start normal for a short time or refuse to start ? Bad capacitors are a common problem in the past , doubt that is cause here but on bench I always run the ESR meter around the power board at least .
You could have a bad CCFL but this young not likely . Did you have a power surge or lightning strike nearby ? A UPS is always a great investment not just a surge bar .
Make sure you power cycle...ie:pull plug from supply and let sit 15 seconds at least . Then try again .

Just some thoughts with out more info .

Return it to the store for a replacement before your warranty expires. There isn't any setting that would correct that kind of noise problem.
